Programmatic LiquidityMechanism
One loop, run once a minute against every token. Fees in at step one, a deeper market for your token at step four.
- 01
Assign
The launch transaction sets the token’s coin creator to an address the protocol generates for that token alone. pump.fun accrues the creator share of every trade to a program account derived from whatever sits in that slot, so the fee stream is pointed at the protocol from the very first trade. Your opening buy, if you make one, is bundled into the same transaction so nothing can land between the two.
- 02
Claim
Once a minute the keeper reads the pending balance for every token it manages and calls collectCoinCreatorFee on anything above the minimum, which moves the accrued SOL into that token’s address. Reading before claiming is what makes this work at launchpad scale: a token with nothing pending costs one lookup instead of a wasted transaction.
- 03
Buy
The claim is split in half and both halves route through Jupiter. One buys your token, the other buys the asset you paired with. These are ordinary market buys on the open market, not transfers out of inventory, which is why the buy pressure is visible in your token’s own chart.
- 04
Pair
Both sides are deposited into a Raydium CPMM pool holding your token against your chosen asset. There is exactly one such pool per pair: the first sweep creates it through the Raydium SDK and its deposited ratio sets the opening price, and every sweep after that deposits into the same pool. Its address is derived from the two mints, so it is always found again rather than duplicated.
One pool, not many
Worth being explicit about, because it is the part that makes the rest worth doing. Your token gets one pool per pair asset, not one per sweep. Sweep one builds it. Sweep two through ten thousand add to it. Reserves only ever go up, so slippage on your token only ever goes down, funded entirely by the volume your token already produced.

The parts worth understanding first.
